Folau maintained a stony silence after earlier holding crisis talks amid RA's threat to tear up his multi-million-dollar contract following his latest attacks on homosexuals.

Supported by his professional netballer wife Maria, the three-time John Eales Medallist spent the morning at a Sydney cafe with Rugby Union Players' Association boss Prataal Raj and another RUPA representative plotting his next move.

He refused to talk when approached by a TV reporter, but it's understood Folau told Raj he wanted to observe his right to challenge RA's planned sacking at a code of conduct hearing.

Rugby Australia later released a telling joint statement with the NSW Waratahs.

"Our joint position regarding Israel Folau is unchanged," it said.

"Following today's meeting, the two organisations will update their respective boards on the matter to consider next steps."

On Friday evening, the NSW Rugby Union doubled down with its own statement, saying Folau had been stood down.

Stood down 'until further notice'

"NSW Rugby Union has stood down Israel Folau from all player duties with the NSW Waratahs until further notice."

RA and NSW Rugby had on Thursday night said Castle had been unable to "directly contact" Folau to advise him of her intention to terminate his $4 million four-year contract.

Castle later took to Twitter to clarify that she'd been in "in constant contact" with Folau's manager Isaac Moses in the 24 hours since his latest social media attacks on homosexuals as well as "drunks, adulterers, liars, fornicators, thieves, atheists and idolaters", who Folau said were all destined for hell.

"He (Moses) did reach Israel, however I was unable to speak with him," Castle tweeted.

"In the absence of compelling mitigating factors, it is our intention to terminate his contract."

Cause of outburst a mystery

Beyond his fierce commitment to his faith, it remains a mystery as to what had motivated Folau to continue his social media outbursts after being warned last year to express his views in a "respectful" manner.

It would seem incomprehensible that the code-hopping ace would risk his career - and the opportunity to win a World Cup this year with the Wallabies - if he didn't have another playing option.
